Cohorts of 2-9 patients receive escalating doses of pulsed dendritic cells IV until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Subsequent cohorts receive cells with or without interleukin-2. One cohort may expand to 15 patients to determine the accuracy of immunologic response to the vaccine.
